Title:
内視鏡システム及び内視鏡検査装置の作動方法
Document Type and Number:
Japanese Patent JP7023368
Kind Code:
B2
Abstract:
An endoscope system 1 includes a plurality of transmission coils 49; a transmission controller 44 that generates a first waveform for detecting a position of an insertion part of an endoscope 10 to be inserted into a subject, and generates a second waveform for detecting a synchronization timing, which is different from the first waveform in at least one of a frequency, a phase, an amplitude, or a waveform shape and is distinguishable from the first waveform; a transmission circuit 46 that drives the transmission coils 49 with the first waveform after driving the transmission coils 49 with the second waveform; a plurality of reception coils 23; an overall controller 40 that acquires a signal corresponding to the first waveform detected by each of the plurality of reception coils 23 on the basis of a timing at which a signal corresponding to the second waveform is detected by the reception coils 23, and derives a position of each of the plurality of reception coils 23 on the basis of the acquired signal.
